Answer:
10 kJ
Explanation:
W = Fd
W = (μN)(vt)
W = μ(mg)vt
W = 0.7(42.9)(9.81)(9)(3.8)
W = 10,075.12506 J
W ≈ 10 kJ
Answer: The level of CO2 has risen.
Explanation:
From the table shown, we can see that the quantity of CO₂ in the atmosphere has steadily risen since the year 1960 going from 317 CO₂PPM in that year to 390 CO₂PPM in 2010.
This is a cause for alarm because with so much carbon dioxide in the atmosphere, there will be an even greater greenhouse effect that will contribute to global warming.
The answer to this question would be: a spring scale.
The spring scale that you use to determine your body weight is actually a device that measures your body gravitational force. The force itself influenced by your body weight, that is why it can determine your body weight.
More weight means more force, more force will shrink the spring more.
The charge of an anti-charm quark is approximately equal to +5.33 ×10⁻²⁰ C.
<h3>What are electrons?</h3>
The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.
The charge on electron is equal to e = -1.6 x 10⁻¹⁹C
The charge of an anti- charm quark is +23 times the magnitude of charge on electron.
So, charge on anti- charm quark is
q = +1/3 x ( 1.6 x 10⁻¹⁹C)
q = +5.33 ×10⁻²⁰ C
Thus, the charge of an anti-charm quark is approximately equal to +5.33 ×10⁻²⁰ C.
